This map is essentially a wrapper for std::vector
. It assigns values to integer keys from the range [0..size-1]
. It can be used together with some data structures, e.g. heap types and UnionFind
, when the used items are small integers. This map conforms to the ReferenceMap concept.
The simplest way of using this map is through the rangeMap() function.
